Abstract

A turbine component has an airfoil (100) extending between a leading edge (56) and a trailing edge (60), and has an outer surface. A coating includes at least two discontinuous areas (54, 62) that are spaced from each other such that there is an area of uncoated surface between the discontinuous areas of coating.
